Gauss Law, Monodromy Defect, Magnetic Lattice Translation, and Lattice Duality
Pengcheng Wei, Yunqin Zheng
In a Hamiltonian lattice gauge theory, the physical Hilbert space is fixed by the Gauss law, by choosing an eigenspace of the Gauss law operator which generates the gauge transform…

Non-invertible Symmetries in Weyl Fermions, and Applications to Fermion-Boundary Scattering Problem
Pengcheng Wei, Yunqin Zheng
We construct a family of non-invertible topological defects in two-dimensional theories of Weyl fermions. The construction relies on the existence of -symmetric conformal bo…
